Hundreds of Southwest flights canceled after two disruptions in 24 hours

Hundreds of Southwest Airlines flights were canceled in the past 24 hours due to a series of technical issues, the airline said, leaving passengers distraught in airports across the country. By Tuesday afternoon, the most recent ground stop had been lifted and Southwest said it was "in the process of resuming normal operations." 

The airline first grounded planes on Monday night after a third-party weather data provider experienced "intermittent performance issues" that kept it from transmitting data required to safely fly planes, the company said.  "While Southwest Teams and the vendor worked to restore connectivity, we implemented a ground stop to protect the Safety of our Crews and Customers," Southwest added.
